Founded in 1982, still growing

Serpentine started with a group of runners training for the 1982 London Marathon. Today we're one of the largest running and triathlon clubs in Britain — a wide mix of ages, from a few juniors to members in their eighties, but still a friendly, small-club feel. Our roots are in road running, but members now race cross country, track and field, and triathlon and multisport up to Ironman distance and beyond.
